ROTARY BOOKING-CHAIR.

Specification ofLetters Patent.

Patented Oct. 13, 1908.

Application filed September 18, 1907. Serial No. 393,500.

To all whom it may concern:

Be it known that I, GUsTAvE G. FREY, of Floyd, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Rotary Rocking- Ohairs and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form part of this specification.

The object of my invention is to provide a rotary rocking chair, whichis simple and eflicient in its mechanical features and well adapted tocarry out the purpose for which it is intended.

Figure 1 shows a side elevation of the chair in what may be termed itsnormal position, with a portion of the back, however, eliminated toreduce the size of the figure. Fig. 2 shows a front elevation of thesame. Fig. 3 is a side elevation of the chair rocked or turned on thevertical pivot with reference to its base, with the mechanism in theposition which it then assumes; Fig. 4 is a partial plan view of thebase. Fig. 5 is a detail side viewshowing the tubular bearing for thecentral vertical pivot of the chair and the posts to which the pedalsare connected. Fig. 6 is a detail front view of the central arm, onwhich the pedals are mounted, and its connected parts. Fig. 7 is adetail view showing portions of the toothed rack-bar and of thehand-lever cooperating therewith. Figs. 8 and 9 are detail front andside views, respectively, of the said hand-lever. Fig; 10 is a detailplan view of one of the pedals. Fig. 11 is a detail view to show thestops by which the movements of the edal arms are limited. Fig. 12 is adetail side view of the central arm, on which the pedals are mounted,and Fig. 13 is a detail side view of one of the pedals and its attachedoperating arm.

Referring to the reference letters and figures in a more particulardescription, 1 indicates a base consisting preferably of cross bars 1",1 having secured on the top a casting providing a vertical tubularbearing 2, centrally located on the base, and posts 3, 3. The seat 4 ismounted by means of a spider frame 5 upon a vertical pivot preferablyformed integral with the spider and received in the vertical bearing 2of the base in such manner as to rotate freely around a vertical axis.Centrally located on the front of the chair is a swinging arm 6 pivotedto a bracket 7 on the underside of the seat and provided with anextension 6, which is also provided with an arm 6 and a pivot 6 forengaging in another bearing or hanger provided on the seat at the edge.The arm 6 may be provided with a segment containing a series of holes asshown, and the same is adapted to receive a hand lever 9 by means ofwhich the arm 6 can be swung into its extended position or folded underthe seat. In order to secure these parts in any desired position ofadjustment, there will be provided on one side of the seat frame asegment of toothed rack 10, having catch teeth, as shown at 10 adaptedto receive a tooth 9 provided on the hand lever 9. The relation of thelever 9 to the swinging arm-6 may be changed by shifting the position ofthe bolt which secures the lever 9 to the part 6 into one of several ofthe holes in the segment before referred to. The arm 6 is provided atits lower swinging end with a pair of oppositely extending conicalpivots 12, which receive the pedals 13, the same being provided at oneend with a conical sleeve or bearing box 13 adapted to receive thepivots 12. The pedals are provided with an angularly-arranged arm 14,which extends in a general upward direction, and are connected at theirupper swinging ends by chains or flexible connections 15 with the topsof the posts 3 before mentioned provided on the base. In order to limitthe downward swinging movement of the pedals 13, there is provided onthe arm 6 a pair of stops 16 against which the pedal arms 14 are adaptedto strike.

As the seat rocks or swings to either side of its normal stationaryposition, the chains 15 in passing from the post 3 to the pedal arms 14are liable to pass so close to the pivotal bearing that pressure on thepedals would have little or no effect in turning the chair on' thepivot. In other words, would be practically on the dead center. To avoidtrouble from this source, there is provided on the rear of the chair aspring 17 attached at one end to the rear of the seat and at the otherend to a spring hanger 18. This hanger is pivoted at 19 to the rearlower portion of the bearing 2 and has a limited swmging movementbetween stops 20. As the seat is rotated with reference to the base, aconsiderable freedom of movement is allowed without bringing into actionthe spring 17,

by reason of the vibration of the spring hanger 18 allowed between theshoulders 20. As the seat swings further around, however, with referenceto the base, towards a point where draft on the chains would becomeineffective, to start the chair in the reversed direction, the spring 17is placed under tension and the re-action of the spring 17 assistsmaterially in starting the chair in a reversal of the swinging movement.

It is obvious that the occupant of the chair, when the pedals are inextended position, may rock the chair on its vertical pivot, first inone direction and then in the other, by pressing alternately on thepedals 13. When, as before stated, the connections 15 are passing closeto the pivot, the operator will be assisted by the spring 17 in rotatingor rocking the chair so as to swing it back and forth horizontally onits central vertical pivot, and the chair seat will, in the absence ofthe application of other power, be brought into a normal positionsubstantially to the front of the base by the action of the spring 17 Inorder to allow the occupant readily to enter or leave the chair, thepedals 13 may be folded or swung inward out of the way, as shown bydotted lines in Fig. 1,, by operating the lever handle 9 in an obviousmanner. In order to support the pedals in their folded position in asubstantial way, there is provided on the front of the base asemi-circular rail or track 21, on which the pedals are adapted to restwhen in folded position.

It is obvious that numerous changes and modifications in and from theconstruction herein described may be made without departing from thespirit of my invention.

What I claim as new and desire to secure by Letters Patent is:

1. The combination, in a chair, of a base, a seat mounted on said baseby means of a vertical pivot centrally arranged beneath said seat,pedals supported from the said seat, and connections from the pedals tothe said base, whereby the occupant is enabled to rock or swing the saidseat back and forth horizontally on the said pivot by alternatelyoperating the said pedals, substantially as set forth.

2. The combination, in a chair, of a base, a seat mounted on said baseby means of a vertical pivot centrally disposed beneath said seat,pedals supported from the said seat, connections from the pedals to thesaid base, and a spring connection between the said sea t and base,whereby the occupant, with the aid of said spring connection, is enabledto rock or swing the said seat back and forth horizontally on the saidpivot by operating the said pedals, substantially as set forth.

3. The combination, in a chair, of a base, a seat mounted on said baseby means of a vertical pivot centrally arranged beneath said seat,pedals supported from the front of the seat, connections from the pedalsto the base whereby the occupant is enabled to rock or swing the saidseat back and forth in the said pivot by operating the said pedals, andmeans for folding the pedals under the seat and extending them tooperative. position, substantially set forth.

4. The combination, in a chair, of a base, a seat mounted on said baseby means of a. vertical pivot centrally arranged beneath said seat,pivoted pedals supported from the said seat in a position to beconveniently reached by the occupants feet and having upwardly extendingarms, and connections from the respective arms of the said pedals topoints on the base, at opposite sides of the seat pivot, substantiallyas set forth.

In witness whereof, I have affixed my signature, in presence of twowitnesses, this 12th day of Sept, 1907.
